I have a 2 second trend with 1 minute history files. When I display history of these files there are gaps every one minute. What is happening here? 

There is a problem with the displaying of history files across file boundaries. Due to a bug introduced into Version 5 there will be a gap on the trend display at the point where the history file changes. This will not happen for trends with 1 second sample period. This is only a problem with the displaying of data - the storing of data works correctly.

CIT has confirmed this to be a problem in Citect for Windows versions 5.00. This problem has been fixed in version 5.00 Service Pack D. When Service Pack D is applied the display of the data will be corrected.
